FOLDING ATTACHMENT FOR CALENDERING-MACHINES.

SPECIFICATION forming part of Letters Patent 0. 732,212, dated June 30, 1903.

Application filed June 12, 1902. Serial No. l l L369. (No model.) A

To all whom, it may concern:

Be it known that I, MAX NEWGARDEN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Folding Attachment for Calendering-Machines, of which the following is a f u1l,clear, and exact description.

The invention relates to calendering-machines employed in cloth-finishing; and its object is to provide a new and improved attachment for use on the feed-table of calendering-machines designed for making bias and other folds in a very simple, quick, and accurate manner on narrow or wide fabrics.

The invention consists of novel features and parts and combinations of the same, as

will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of a calendering-machine with the improvement applied thereto. Fig. 2 is an enlarged plan view of the improvement. Fig. 3 is an enlarged cross-section of the same on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of one of the covering-plates. Fig. 5 is a like view of another covering-plate of smaller size, and Fig. 6 is a perspective view of oneof the false bottoms.

The calcndering-machine on which the improvement is used is of usual construction and is mounted on a frame A, in which are journaled the calendaring-rollers B and 0, between which passes the fabric D to be calendered, and the attachment, presently to be described in detail, for forming the folds 0n the fabric D previous to its passing between the rollers B and O is removably secured to the feed-table E of the calendering-machine. The attachment consists, essentially, of a guide F in the shape of a plate, having on its bottom a spring G for engaging the under side of the feed-table E, while the inner end of the guide F rests on the top of the guide- H and I for Wider or narrower fabrics. The

movable guidewayI is secured on tongues I, mounted to slide transversely in suitable bearings formed in the guide F, and the said tongues I, and with them the guideway I, are

secured in place after the desired adjustment is made by a set-screw J screwing in the permanent guidewayH against one of the tongues I. The tongues Iare preferably united with each other at one side of the attachment and form a handle 1 adapted to be taken hold of by the operator to move the guidewayl in or out of position'for the purpose hereinafter more fully described.

On the top of the guide F is removably held a false bottom K, provided with sidewise-ex- 7o tending pins K, adapted to rest against the outer ends of the guideways H and I to hold the false bottom against movement on the guide. A number ofsaid false bottomsKof diflerent widths are employed for narrower or wider goods. For cloth or other fabrics of extra thickness the false bottom is removed to accommodate the device to the extra thickness of the fabric.

It will be readily apparent that various 8o widths or thickness of cloth may be folded in the attachment when these false bottoms are employed. For instance, if it is desired to fold a very thin piece of material, such as silk, it might be-necessary to have several of these'false bottoms in order to press the folded edge of the material tightly between the guideway and the removable cover; but if a wool textile is to be folded, being much thicker than the ordinary cloth, the false bot- 9o toms may be removed to accommodate the increased thickness.

A cover L of a corresponding width to the false bottom K is placed on top of the fabric extending over the false bottom K and the guide F, and this cover L extends with its side edges into the longitudinal grooves of the guideways H and I, so that the side edges 3 table E. One side of the guide F is provided 5c of the fabric fold over onto the top of the cover L, as will be readily understood by reference to Fig. 3. A number of covers L of different widths are employed, the widths of the covers corresponding approximately to the widths of the different false bottoms K. On the top of each cover L and near the front end thereof at the middle is secured a post L, on which is fastened a cross-bar L adapted to abut against pins N N, projecting upwardly from the guideways H and I, so as to limit the inward sliding movement of the cover L when the device is in use, it being understood that the fabric passing between the calender-rollers B and G exerts an inward pull on the cover L until the cross-bar L rests against the pins N N.

The device is used as follows: The guide F is clamped in position on the feed-table E, so as to stand approximately at right angles to the axes of the rollers 13 and O, and then the strip of fabric is placed on the false bottom K, held on the guide F, after which the corresponding cover L is placed on top of the fabric and the sides thereof folded over the same, so that one side edge of the cover can be pushed into the permanent guideway H, and then the other guideway I is moved over to engage the opposite edge of the cover L with the fabric thereon by the operator manipulating the handle I correspondingly. When this has been done, the set-screw J is screwed down to fasten the guidewayI in position. The forward end of the fabric is now drawn forward by hand until it passes between the rollers B and O, which in rotating draw the fabric between the rollers, and thus calender the folds down upon the body of the fabric, it being understood that as the fabric is drawn along the folds form themselves by the action of the cover L and the guideways H and I. It is usually only necessary for the operator to hold one or more fingers on the top of the fabric in the rear of the cover L, so as to insure proper formation of the folds by the cover L and the guideways H and I. Now for fabrics of different widths differentsized false bottoms K and covers L are employed, as previously explained.

By the attachment described the folds are very accurately formed on straight as well as bias cut strips of fabric materials, and the folds are immediately calendered by the action of the calendering-rollers B and C. It will also be readily understood that by the arrangement described the several parts can be quickly changed to permit of using the device for forming folds of narrower or wider fabrics.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A folding attachment for calenderingmachines, comprising a base-plate having guideways on opposite sides for guiding the fabric to the rollers, a stop or abutment on said guideways, a cover removably held on the base-plate and extending with its sides into the guideways, to fold the' sides of the fabric over, previous to the fabric passing between the rollers of the calendering-machine, and a bar on the cover extending transversely thereof and abutting against the stops on the guideways for limiting the movement of the cover in said guideways.

2. A folding attachment comprising a grooved base-plate having a fixed guideway on one side, a second guideway provided with a transversely-arranged support sliding in said grooves in the base-plate, and a cover removably held on the base-plate and extending with its sides into the guideways.

4.. A folding attachment comprising a grooved base-plate, having a fixed guideway at one side, a guideway for the other side of the plate sliding in said grooves in the plate,

a false bottom removably held on the baseplate between the guideways, and a cover removably held on the base-plate over the false bottom and extending with its sides into the guideways.

5. A folding attachment comprising a grooved base-plate having a fixed guideway on one side, a guideway on the other side of the plate mounted to slide transversely in the grooves in the plate, means on the permanent guideway for fastening the movable guideway in position after adjustment, and a cover removably held on the plate and extending With its side edges into the guideways.
